WINDOW-VENTILATQB'ATTACHMENT.

Application filed. October 25.

To all whom it may concern:

Be it known that I, GEORGE E. MERRILL, a citizen of the United States, residing at Salem, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in WVindow-Ventr lator Attachments, of which the following is a specification.

This invention relates to improvements in ventilator attachments for windows and it is the principal object of the invention to provide a device capable of being arranged in a window in amanner to permit the ingress of sufficient fresh air to maintain the room communicating therewith at a comfortable and healthful temperature and without alteration to the window or any parts thereof.

Another and equally important object of the invention is to provide a ventilator attachment which can be easily and quickly adjusted to regulate the flow of fresh air therethrough into the room communicating therewith.

Other objects will be in part obvious and in part pointed out hereinafter.

The improvements in the details and arrangement of parts will be apparent from an inspection of the accompanying drawings when considered in connection with the specific description hereinafter contained and wherein a preferred embodiment of the invention is shown for the purpose of imparting a full understanding thereof.

In the drawings:

Figure 1 is a front elevation of the attachment as applied to a fragment of a window,

Fig. 2 is an enlarged vertical transverse section therethrough, and

Fig. 3 is a perspective view of the attachment.

Having more particular reference to the drawings, in connection with which like reference characters will designate corresponding parts throughout the several views, W indicates the window to which the attachment is applied in its entirety, said attachment being preferably engaged with a baseboard 1, which board is of a size to permit its arrangement, in the window frame in a manner as clearly shown in the Fig. 1 and is formed with an opening intermediate its ends, adjacent which the ventilator attachment is positioned.

The improved ventilator attachment m- Specification of Letters Patent.

1918. Serial No. 259,672.

cludes a tapered housing 2 having an open side wall and an open top, the open side wall thereof having apertured flanges 3 arranged thereabout to permit the securing of the attachment to the baseboard 1 as shown in the Figs. 1 and 2 by passing nails or other securing devices through the flanges into engagement with the board. Oppositely disposed ways 4 are formed adjacent the side portions of the open top of the casing 2 and aline with a slot formed in one end wall thereof whereby to permit the arranging of a slidable closure plate 5 therein, said plate carrying a'knob, cleat or other suitable form of handle for an obvious purpose. In this connection, attention is directed to the fact that the slidable closure plate 5 is arranged parallel to the adjacent face of the baseboard 1 and in consequence movement of the same to full or partly open positions or to full or partly closed positions can be easily and quickly effected by a user.

In using the device, as hereinbefore stated, the baseboard 1 is arranged in the lower portion of the frame of the window W whereupon the lower marginal portion of the adjacent sash is engaged with the upper edge of said baseboard, thus effectually closing the window. However, by moving the slidable closure plate 5 to the desired position, ingress of fresh air to the room communicating with the device will be permitted to such extent as desired by the user.

The device by reason of its simple and compact construction can be applied to practically any form of window without alteration thereto and will be found to be advantageous and beneficial for use in connection with the rooms of a building, especially, sleeping compartments. By reason of the tapered formation of the casing 2, the beating of rain or snow into a room, the window of which is provided with the attachment, will be positively prevented, since, the same upon striking the inclined inner wall of the casing will quickly drain therefrom.

Manifestly, the-construction shown is capable of considerable modification and such modification as is within the scope of my claims, I consider within the spirit of my invention.

I claim:

A. ventilator attachment of the character described, comprising a base board adapted Patented. June 1, 1920.

to be engaged between the side portions of a Window frame and having an opening an open top, the inner wall of said casing being inclined, and a closure plate slidably engaged with the casing adjacent the open top and arranged parallel with the adjacent face of said base board. 7 10 In testimony whereof I affix my signature hereto.
